- BaseChatMesh/ContactInfo/ChannelDetails restored to upstream text, ZephCore
changes fenced; added to the Shared-file list
- upstream names: handleCmdFrame, writeOKFrame/writeErrFrame,
addToOfflineQueue, queueMessage; dead dequeue removed
- handleCmdFrame split into handleCmd<Name>() in upstream order;
CMD_SEND_PATH_DISCOVERY -> _REQ
- CompanionMesh::handleCommand as the single CLI entry point; over-the-air
TXT_TYPE_CLI_COMMAND from flag-0x10 contacts (upstream command set only)
- V-contact moved to app/VContact.cpp, protocol constants to
app/CompanionProtocol.h; comment diet (image-identical)
